timestamp array

Array of 64-bit timestamps returned from the RT Get Timestamp node that you want to analyze.

calibration array

An array used to account for the time required for the RT Get Timestamp node to execute. The RT Timestamp Analysis node subtracts the mean value of all elements in calibration array from each element in timestamp array to remove the timestamp errors introduced when the RT Get Timestamp node adds the element to the timestamp array in memory on the RT target.

warmup iterations

Number of timestamps to ignore from the beginning of timestamp array. Use Warmup iterations to remove initial timestamps from the beginning of timestamp array that might have been affected during the initial execution of the application on an RT target.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error

error in contains an error

If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error

mean time (μS)

Average execution time for the values in the execution times array.

standard deviation (μS)

Standard deviation for the values in the execution times array.

execution times (μS)

Execution time, in microseconds, between each element of timestamp array.

execution histogram

Histogram values for the elements of execution times.

max jitter (μS)

Maximum deviation between elements of execution time and the value of mean time. The value can represent a positive or negative deviation.

error out

Error information.

The node produces this output according to standard error behavior.
